Description
Background technology
Wireless mobile telecommunication technology is used various standards and agreement to transmit data between transfer station and portable radio device.Some wireless devices communicate via physical layer, use OFDM (OFDM) digital modulation scheme.OFDM standard and agreement can comprise third generation partner program (3GPP) Long Term Evolution (LTE), (it is called WiMAX (global microwave access intercommunication) and IEEE 802.11 standards (it is called WiFi by industrial community conventionally) by industrial community to Institute of Electrical and Electric Engineers (IEEE) 802.16 standards (for example 802.16e, 802.16m) conventionally.In the 3GPP of LTE system radio access network (RAN), transfer station can be the combination of the radio network controller (RNC) in evolved universal terrestrial radio Access Network (E-UTRAN) Node B (be typically expressed as again enode b, strengthen Node B, eNodeB or eNB) and E-UTRAN, and it communicates with the portable radio device that is called subscriber equipment (UE).Down link (DL) transmission can Shi Cong transfer station (or eNodeB) to the communication of portable radio device (or UE), and up link (UL) transmission can be the communication from portable radio device to transfer station.In downlink transmission, transfer station can adopt clean culture subframe, by unicast services, come to communicate with single portable radio device.Alternatively, transfer station can adopt multicast/broadcast Single Frequency Network (MBSFN) subframe, use multicast broadcast multimedia service (MBMS) to come to communicate with a plurality of portable radio devices.

Example embodiment
The initial general introduction of technology embodiment is provided below, and then describes in more detail concrete technology embodiment.This initial general introduction estimates to help reader to understand quickly this technology, rather than estimates to determine key feature or the essential feature of this technology, neither limit the scope of claimed theme.
Along with having the surge of the mobile device of video capability, conference call becomes the more and more general method communicating with other video-telephone system and other mobile device.In 3GPP LTE network, in multicast/broadcast Single Frequency Network (MBSFN) subframe, use multicast broadcast multimedia service (MBMS) to support multicast and broadcast.Multicast is from source simultaneously to one group of destination apparatus pass-along message or information in single transmission.Broadcast is illustrated in single transmission from source simultaneously to larger one group of destination apparatus pass-along message or information.Multicast can comprise broadcast.Internet Protocol (IP) multicast service can be used in the point-to-multipoint transmission of user grouping.MBSFN subframe can be effectively to more audience's instant broadcast, but may not be effective to other multicast service, for example video conference service.Conventionally in LTE network, use the unicast services of clean culture subframe during video conference, to be used for transmitting one by one downlink video to each user (via mobile device).Unicast services can be inefficient mechanism to transmitting some multicast services, and it can be by using clean culture subframe to repeat to each mobile device transmission the radio resource that radio access network (RAN) wasted in multicast grouping separately.
In addition, the MBMS in MBSFN subframe may the Bu Huiyu eNodeB of family (HeNB) compounding practice.HeNB can be can carry out eNodeB permitted multi-functional picocell or Femto cell (low power base station), but HeNB can be optimized or be designed for family or office.Picocell can be arranged in little of medium size structure, for example, in office, shopping mall, railway station, stock exchange or aircraft.Femto cell can be arranged in the minor structure such as family or small enterprise.In one example, Femto cell can have 200 meters of scopes within (m).In another example, 16 movable mobile devices altogether can be supported in Femto cell, and can have the scope within 50 m.
Multicast service can be carried out by clean culture subframe.Clean culture subframe can be non-MBSFN subframe (or non-MBMS subframe).Conventionally, mobile device business is used clean culture subframe, unless subframe is preserved for to MBSFN subframe (or MBMS subframe).Transfer station can be used clean culture control channel, for example physical downlink control channel (PDCCH) to a plurality of mobile device communicating control informations of multicast service.Transfer station can be used unicast data channel, for example physical down link to share data channel (PDSCH) to a plurality of mobile devices transmission data of multicast service.Mobile device can use clean culture control channel, for example physical uplink control channel (PUCCH) to transmission, to transmit the control information of multicast service.
For multicast service, transfer station (eNodeB) can be used control plane agreement, for example radio resource to control (RRC) and set up the connection between each mobile device in multicast group.Multicast group can provide service by the combination of single transfer station (eNodeB) or transfer station (eNodeB).Transfer station can set up multicast service to a plurality of mobile devices in multicast group with multicast identifier.Multicast identifier can be unique.Multicast identifier can be the multicast cell-radio network temporary identifier (MC-RNTI) with common cell identifier (CID), but also can use other identifier.As a part for the foundation of multicast service, transfer station can be used information element (IE) the multicast configuration in RRC signaling, notifies each mobile device in multicast group about multicast identifier.
In one example, transfer station can be different physical uplink control channel (PUCCH) resource of each mobile device assignment in multicast group for acknowledge character (ACK) or the indication of Negative Acknowledgement character (NACK) feedback resources.PUCCH can carry control information in ul transmissions.Then, transfer station can with the IE PUCCH in RRC signaling, configure to notify each mobile device in multicast group about it PUCCH resource assignation for ACK or the indication of NACK feedback resources.In another example, transfer station can come for the subset assignment of the mobile device in the multicast group different PUCCH resources for ACK or the indication of NACK feedback resources based on transmission quality factor.In another example, the scrambling seed that transfer station can initialization scrambler, for coming scrambling physical downlink control channel (PDCCH) and/or physical down link to share the data of data channel (PDSCH) with MC-RNTI.Then, PDSCH resource can be joined for multicast component with the PDCCH sheltering by MC-RNTI by transfer station.In addition, MC-RNTI can be used for the data in PDCCH and/or PDSCH to carry out descrambling.
Mobile device can receive from transfer station the MC-RNTI of the CID with multicast group.Can use between IE multicast in RRC signaling configuration, a plurality of mobile devices in multicast group and share MC-RNTI.As a part that receives MC-RNTI, mobile device can receive the PUCCH resource assignation for ACK or the indication of NACK feedback resources.The PUCCH resource assignation of mobile device can be different from the PUCCH resource assignation of other mobile device in multicast group.Then, mobile device can receive the PDCCH sheltering by MC-RNTI from transfer station.Mobile device can carry out blind Detecting PDCCH with MC-RNTI.
In the PDSCH that transfer station can configure at PDCCH, transmit data.Travelling carriage can receive the transmission of the data in the PDSCH that PDCCH configures.After the transmission of data that travelling carriage can be in receiving PDSCH, transmit ACK or NACK feedback.
Transfer station can receive ACK or NACK feedback from least one mobile device.Transfer station can be when receiving NACK feedback data retransmission.Transfer station can limit to send one or two re-transmission according to the delay of application.Re-transmission can be encoded to retransmitting with identical MC-RNTI.As the part retransmitting, mobile device can carry out soft merging by the grouping newly receiving and the grouping previously receiving.For single community example, transfer station can be used cell specific reference signal (CRS) or UE specific reference signals (UE-RS) (demodulated reference signal (DMRS)) to transmit and/or data retransmission.PDCCH can transmit in the control area of subframe, or PDCCH can use the control signal based on DMRS to transmit.For many communities example, transfer station can be used CRS or UE-RS (DMRS) to transmit and/or data retransmission.When using CRS, can forbid CRS and interweave.For He Duo community, single community example, can in the control area of subframe, transmit PDCCH.Alternatively, PDCCH can use the control signal based on DMRS to transmit, and wherein PDCCH can have the micro diversity gain similar to data.Community can be the combination of down link and/or uplink resource.Community can be exclusively used in multicast transmission or unicast transmission.Community can also be configured to support multicast and unicast transmission.
In another example, when the subset mobile device the subset of the mobile device from multicast group receives NACK feedback, transfer station can be used mixed automatic retransfer request (HARQ) to carry out data retransmission.When cyclic redundancy check (CRC) (CRC) failure, subset mobile device can transmit NACK feedback.When signal and interference and noise ratio (SINR) are during lower than the predeterminated level of subset mobile device, CRC can failure.
Multicast service can be used in Huo Duo community, single community.Fig. 1 illustrates the transfer station 210 of single community 212.Each mobile device 220A-D can with transfer station radio communication.Fig. 2 illustrates a plurality of 210A-C of transfer station of a plurality of communities (or many communities) 212A-C.Mobile device 220E-H can be via transfer station and each cell wireless communication 230.Multicast service can greatly be saved to radio resource for the downlink transmission of conference call.Under many cell conditions, can also improve performance by the interference reducing near community.
Wireless communication system can be subdivided into various parts (being called layer).In LTE system, communication layers can comprise physics (PHY), media access control (MAC), radio link control (RLC), PDCP (PDCP) and radio resource control (RRC) layer.Physical layer can comprise the basic hardware transmission assembly of wireless communication system.
The basic hardware transmission assembly of reflector can comprise: channel encoder, for protect binary system input data by coding; Interleaver or scrambler, for interweaving for decay; Mapper, for improvement of reliability; Beam-former, for being separated into layer by institute's mapping (enum) data; Invert fast fourier transformation (IFFT) modulator, for being modulated to time domain data the OFDM symbol of frequency domain; Digital to analog converter (DAC), for converting modulation signal to analog signal; Radio frequency (RF) reflector, for transmitting analog signal.
The basic hardware transmission assembly of receiver can comprise: RF receiver, for receiving analog signal; Analog to digital converter (ADC), for converting analog signal to modulation signal; Fast fourier transform (FFT) demodulator, for being time domain data by the OFDM symbol demodulation of frequency domain; Channel estimator, for estimating channel and/or estimating the Noise and Interference that channel occurs; Multiple-input and multiple-output (MIOMO) decoder, for combined demodulation signal; Remove mapper, deinterleaver or descrambler; Channel decoder, for generating binary system output data.The physical layer of reflector and/or receiver can comprise other assembly, for example (S/P) transducer, also-string (P/S) transducer, Cyclic Prefix (CP) inserter and canceller, guard band inserter and canceller and other expection assembly of string-also.
In one example, data in wireless mobile communications can be used general Long Term Evolution (LTE) frame structure by transfer station (or eNodeB), in downlink transmission, on physics (PHY) layer, send mobile device (or UE) to, as shown in Figure 3.Although LTE frame structure is shown, also can uses for IEEE 802.16 standards (WiMax), IEEE 802.11 standards (WiFi) or use the frame structure of communication standard of the another kind of type of OFDM.Ul transmissions can have the frame structure similar to downlink transmission.
In the example depicted in fig. 3, the radio frame 100 that is used for transmitting the signal of data can be configured to have the duration T of 10 milliseconds (ms)
f.Each radio frame can segmentation or is divided into is respectively ten long subframe 110i of 1 ms.Each subframe can be further subdivided into the duration T respectively with 0.5 ms
slottwo time slot 120a and 120b.The first time slot (#0) 120a can comprise physical downlink control channel (PDCCH) 160 and/or physical down link sharing channel (PDSCH) 166, and the second time slot (#1) can comprise the data of using PDSCH.Each time slot of the component carrier being used by cell site and receiving station (CC) can comprise a plurality of Resource Block (RB) 130a, 130b, 130i, 130m and the 130n based on CC frequency bandwidth.CC can have carrier frequency, and it has bandwidth and centre frequency.Each RB (physics RB or PRB) 130i can comprise 12-15 kHz subcarrier 136 (on frequency axis) and each subcarrier 6 or 7 OFDMs (OFDM) symbol, 132 (on time shafts).If adopt short or standard cyclic prefix, RB can be used seven OFDM symbols.If use extended cyclic prefix, RB can be used six OFDM symbols.Resource Block can be mapped to 84 resource elements (RE) 140i by short or standard cyclic prefix, or Resource Block can be mapped to 72 RE (not shown) by extended cyclic prefix.RE can be the unit that an OFDM symbol 142 is multiplied by a subcarrier (that is, 15 kHz) 146.In the situation that Quadrature Phase Shift Keying (QPSK) is modulated, each RE can transmit two position 150a and the 150b of information.Can use the modulation of other type, the position of for example using 16 quadrature amplitude modulation (QAM) or 64 QAM to transmit greater number in each RE, or use bi Phase Shift Keying (BPSK) is modulated at the position (single position) of transmitting smaller amounts in each RE.RB can be configured for the downlink transmission from eNodeB to UE, or RB can be configured for the ul transmissions from UE to eNodeB.
Reference signal can be by OFDM symbol, via the resource element in Resource Block, usually transmit.Reference signal (or pilot signal or sound) can be the known signal using because of a variety of causes, for example, in order to estimate channel and/or to estimate the noise in channel.Reference signal can be received and be transmitted by cell site and mobile communications device.Dissimilar reference signal (RS) can be used in RB.For example, in LTE system, downlink reference signal type can comprise cell specific reference signal (CRS), multicast/broadcast Single Frequency Network (MBSFN) reference signal, UE specific reference signals (the specific RS of UE or UE-RS) or demodulated reference signal (DMRS), location reference signals (PRS) and channel state information reference signals (CSI-RS).
CRS can transmit in the community of supporting PDSCH in downlink subframe.Data send UE via PDSCH to from eNodeB.PDCCH is used for transmitting down link control information (DCI), and its notice UE distributes or scheduling about the relevant resource of the down-chain resource assignment on PDSCH.PDCCH is also used for transmitting uplink control information (UCI) (its notice UE grants about uplink resource) and up-link power control command.PDCCH can transmit each subframe that sends UE from eNodeB to before PDSCH.MBSFN reference signal can be transmitted when Physical Multicast Channel (PMCH) transmits in MBSFN subframe.UE-RS or DMRS can transmit in the downlink subframe of supporting PDSCH.UE-RS (DMRS) can transmit for during the downlink sharied signal channel of particular terminal (mobile communications device) (DL-SCH) is transmitted to assigned Resource Block, be used for using the single UE of a plurality of antennas to carry out wave beam formation, and for PDSCH demodulation.PRS can be in being configured for the downlink subframe of PRS transmission, in RB, transmit, but can not be mapped to Physical Broadcast Channel (PBCH), master sync signal (PSS) or auxiliary synchronous signal (SSS).CSI-RS can be used in downlink channel quality.
Utilize this background of physical layer descending chain circuit and uplink channel, can in another example, describe the multicast service framework that uses clean culture subframe.Fig. 4 illustrates the instantiation procedure that uses transfer station (eNB) and three mobile devices (UE1, UE2 and UE3), the multicast service in clean culture subframe.ENB can set up with the RRC of each UE in multicast group and be connected 302a, 302b and 302c.Although three UE are shown, and any amount of UE can form multicast group.RRC signaling was controlled control plane signaling via the 3rd layer of communication link before the PDCCH that sends subframe.The RRC agreement of UE and function can comprise that the broadcast, the radio bearer that are connected foundation and release, system information are set up/reconfigured and be connected mobile process, page notification and release with release, RRC and/or exterior ring power is controlled.RRC signaling also can be used for scheduling and search for the PDCCH search volume of using in blind decoding.A RRC connects and can to UE, open at any given time.RRC connects foundation can be used for carrying out the transformation from RRC idle pulley to RRC connection mode.Each UE for example, in delivery applications data (browsing internet, transmission or reception Email or video conference) or complete the transformation that signaling procedure proceeds to RRC connection mode before.RRC connects process of establishing can be initiated by each UE, but can be triggered by UE or network.RRC signaling can be set up message (it can define the configuration information of PDSCH, PUCCH and PUSCH physical channel) and transmit via information element (IE), for example RRC connection.
ENB can define the MC-RNTI of the CID with each multicast group.Cell-radio network temporary identifier (C-RNTI) allow eNB identification UE and with UE direct communication.C-RNTI can be the UE identifier being distributed by eNB, and at that eNB, to control in Yi Ge community be unique.When UE moves to new community, can redistribute C-RNTI.Common CID allows each UE in community identical downlink transmission to be received the decode simultaneously.ENB can notify each UE that participates in multicast group about MC-RNTI by RRC signaling.In other words, eNB can set up multicast service to each UE in multicast group by the RRC signaling that comprises IE multicast configuration 304a, 304b and 304c.IE multicast configuration can comprise the MC-RNTI with common CID.
In another example, the different PUCCH resource assignations that each UE can be indicated for ACK/NACK feedback resources by eNB assignment
, wherein n is the subframe numbers for HARQ-ACK transmission on antenna port p for the PUCCH form 1a/1b of Frequency Division Duplexing (FDD) (FDD) or time division duplex (TDD) ACK/NACK feedback.ENB can with the IE PUCCH in RRC signaling, configure to notify each UE in multicast group about it PUCCH resource assignation for ACK or the indication of NACK feedback resources.In another example, transfer station can be based on transmission quality factor, for example, lower than the Signal to Interference plus Noise Ratio (SINR) of predeterminated level or indicate the level of bad cqi (CQI) report, bad leading matrix index (PMI) report or bad transmission rank index (RI) report, comes for the subset assignment of the UE in the multicast group different PUCCH resources for ACK or the indication of NACK feedback resources.Also can use other transmission quality factor.
ACK can Shi You receiving station (UE) response cell site (eNB) transmission of messages and as the transmission control character of confirming that (that is, the positive response to dispatching station) transmits.When not having correct receipt message or error of transmission to occur, NACK can be transmitted by receiving station or mobile device.NACK can automatically generated after having expired for receiving the scheduled time of ACK or NACK by eNB.The scheduled time can be by eNB or set default time of UE, or this time can by generate the data that will transmit should be used for determine.Mixed automatic retransfer request (hybrid ARQ or HARQ) can be that two-forty forward error correction coding and HARQ (ARQ) mistake are controlled the combination of (for detecting but not repairable mistake).In standard A RQ, use error detection code, for example cyclic redundancy check (CRC) (CRC) redundant digit to be added to the data that will transmit.In HARQ, can use code, it can also carry out forward error correction (FEC) (for example Reed-Solomon code, convolution code or spy broadcast code) except error detection (ED), to correct vicious subset when relying on ARQ, for correcting the not repairable mistake of redundancy of using initial transmission to send.Therefore, HARQ can show better than common ARQ in bad signal conditioning, but can take obviously in good signal condition more poor throughput occur as cost.
ENB can dynamic assignment resource, and to each UE (UE1, UE2 and UE3) in multicast group, transmits PDSCH 306a, 306b and 306c (its can each UE in multicast decode) in single transmission.The further details of step 306a, 306b and 306c is provided, and eNB can send PDCCH and distribute for the resource of PDSCH.PDCCH can shelter by MC-RNTI.MC-RNTI or C-RNTI can be used to allow UE to receive the transmission of estimating to be sent to UE by encoder or scrambler.Sheltering PDCCH allows the UE with coupling MC-RNTI to decode to message.The scrambling seed of scrambler or decoder can carry out initialization with the MC-RNTI with common CID, for example CID=0, to payload is carried out to scrambling, wherein payload can be the data on PDSCH.Data, for example conference call can transmit via PDSCH.
At UE, each UE can be used the MC-RNTI of previous transmission to carry out blind Detecting (blind decoding) to PDCCH.For multicast allocation example, each UE can decode to PDCCH and PDSCH, and to eNB feeding back ACK/NACK response 308a, 308b and 308c.When enabling ACK/NACK feedback, if error of transmission occurs, eNB can resend messages 310.Error of transmission can feed back to indicate by NACK.Re-transmission can offer all UE in multicast group or the subset of the UE in multicast group based on some subset standard, for example transmission quality factor.For example, eNB can limit to send one or two re-transmission according to the delay of application.Re-transmission can send with unicast or multicast transmission.In another example, can not enable ACK/NACK feedback, and the re-transmission of message can not carried out.
UE can carry out blind decoding, because can only notify the quantity of UE about the OFDM symbol in the control area of subframe, and can for it, not provide the position of the corresponding PDCCH of UE.UE can by being called the process of blind decoding in each subframe monitoring and decoding PDCCH candidate collection (quantity of the OFDM symbol in the control area of subframe) to obtain DCI, search the PDCCH of UE.
At receiver end (UE of down link), carry out separating precoding, symbol combination, meet after demodulation disturbs, UE can carry out blind decoding in PDCCH payload, because UE may not know detailed control channel structure, comprise the quantity of control channel and it is shone upon to the quantity of the control channel element (CCE) of each control channel (CCH).A plurality of PDCCH can transmit in single subframe, and it is can be all relevant to particular UE and can not be all relevant with particular UE.UE can, by the PDCCH candidate collection (can shine upon the set of the continuous CCE of PDCCH on it) in each subframe of monitoring, search the specific PDCCH of UE.UE can be used its radio net temporary identifier (RNTI) candidate is attempted and decode.RNTI can be used for PDCCH candidate's cyclic redundancy check (CRC) (CRC) to carry out demasking.If crc error do not detected, UE can regard PDCCH candidate as that successfully decoding is attempted, and can read successfully the control information in candidate.
For single community example, eNB can be used CRS or UE-RS (DMRS) to transmit and/or retransmit multicast service data.For many communities example, eNB can be used CRS or UE-RS (DMRS) to transmit and/or data retransmission.If use CRS, the CRS that can stop using interweaves.CRS interweaves and CRS and/or data can be carried out to cell specific frequency shift v
shift, it is applied to specific cell and cell number.Owing to can using a plurality of communities, so interweaving, CRS may shall not be applied to the multicast service of a plurality of communities.Interleaver can be carried out CRS and interweave.For many communities example, a plurality of eNB can have the similar configuration of RLC, MAC and/or the PHY layer of multicast service, and therefore many cell transmission can have for the synchronization of radio frame timing of same systems frame number (SFN) or the radio frame timing of coordinating.
Except the option of having discussed, when the user's who relates in multicast group quantity is larger, also can use at least two ACK/NACK feedbacks and HARQ to retransmit option.In one example, eNB can, based on certain standard, for example transmission quality factor or weak SINR, enable ACK/NACK and HARQ re-transmission to user's subset.PUCCH resource assignation in multicast configuration MAC IE
therefore can offer the subset of the UE in multicast group, can be only just effective from the ACK/NACK feedback of subset UE.In another example, the ACK/NACK that can stop using, this can be similar to MBMS framework.ACK/NACK feedback is not used in MBMS transmission.MBMS framework can not used blind HARQ to repeat or radio link control (RLC) repeats fast.
Compare with MBMS in special-purpose MBSFN subframe or the unicast services in clean culture subframe, use the multicast service of clean culture subframe can be more effective, and larger reliability is provided.Use the multicast service of clean culture subframe to can be used in HeNB.Use the multicast service of clean culture subframe without cell-specific, providing multicast service in multicast transmission in the situation that.MBMS or unicast services for example, can not be all effective in the small group (small office) of multicast users of supporting to wish transmitting (it can feed back to provide by ACK/NACK).
